Jeremy Bobbin 972ca8ab94 fix bug where attaching to dead session won't give underlying exit code 
If dvtm dies, and you run `:|abduco -a session`, abduco will often exit
without giving you the exit code, and without removing the socket from
~/.abduco.

We resolve this by first sending the client either an EXIT or an empty
CONTENT packet.

Only after the client recieves it, we set the socket to non-blocking.

Marc André Tanner c901f2bbb8 If stdin is not a terminal pass-through its data to the session 
This allows to send commands to a running session:

    echo cowsay hi | abduco -a session

See #8 for initial discussion of the feature.

Marc André Tanner 3e3308d4e3 Only manipulate output terminal state if it is a terminal 2018-03-17 13:30:51 +01:00
Marc André Tanner fdbda93131 Correct EOF handling on client stdin 
Previously we would end in an infinite loop which might be the cause
of #15.

Marc André Tanner 482237919b Fix length of MSG_RESIZE packet 
We no longer send the complete struct winsize.

Marc André Tanner 8964601fe1 Use fixed size integer types in protocol messages 
This should make it possible to connect with a 32bit client to a 64bit
server. This might also make it possible to forward the abduco socket
over SSH as described in #25. Different endianness are not supported at
this time.

This is a breaking protocol change. Make sure to use the same version
as client and server (anything else is unsupported anyway!).

Marc André Tanner e671c024c9 Only test for redraw key if it is actually configured 
This should make CTRL-Space work by default.

Marc André Tanner f7b65db3ca Make cursor visible after client termination 
For complex interactive application it is recommended to run them
under dvtm as in:

 $ abduco -c demo dvtm [your-fancy-app]

Marc André Tanner 577ae6ae7a Slightly tweek communication protocol for -l option 2016-01-03 12:03:02 +01:00
Luke Clifton 1fcd6e4f44 Added -l option to move clients to the bottom of the stack. 
This means it wont take control over the window size until
it is the last remaining one, unless another client connects
with the -l option set at a later time.

Marc André Tanner 76bae5939f Improve terminal restoring 
Instead of simply moving the cursor to the bottom of the screen
use the alternate screen buffer i.e. the smcup/rmcup capabilities.

This is currently hardcoded to the xterm originated \e[?1047{h,l}
sequence. I also patched dvtm to support these.

Marc André Tanner 2de1946f1a Use pselect instead of select 
For the server case I see no such race condition.

Marc André Tanner ed4f1ecdcd Use the same packet structure for both ways of the client server communiction 
This is slightly less efficient than before but allows the server
to send different types of messages not only output data to the
client.
